Linear work is F*D and rotation is 1/2Iω2, but if a problem as me rotational energy (Rotation worl = KE?) of a wheel and I have the linear work, can I just set Wrotation=Wlinear?
If I have Work1=F*D, can I use that answer to be equal to W2(=1/2Iω2)?marcusl said:Please correct the errors in your post, your question is not understandable as written.
Thanks. Now is it possible to find angular momentum from just work and force? no radius, speed, nor mass are given. If so, how?russ_watters said:Linear and rotational work can be equated, yes.
No, you need at least radius or angular speed.Just_enough said:Thanks. Now is it possible to find angular momentum from just work and force? no radius, speed, nor mass are given.
Yes and no. Both rotational work and linear work involve the transfer of energy to an object in order to cause it to move. However, the direction of this movement is different - rotational work involves movement along a circular path, while linear work involves movement along a straight line.
Yes, rotational work can be converted into linear work. This can be seen in everyday objects such as a bicycle - the rotational motion of the pedals is converted into linear motion of the wheels. This conversion is possible through the use of gears and other mechanisms.
No, the units for rotational work and linear work are different. Rotational work is typically measured in joules (J), while linear work is measured in newton-meters (N-m) or joules (J). This reflects the difference in direction of the movement involved in each type of work.
Both rotational work and linear work are commonly used in everyday life. However, linear work is perhaps more commonly encountered, as it is involved in activities such as pushing a shopping cart, lifting weights, or running.
Yes, there are many real-life examples where rotational work and linear work are used together. One example is a car engine - the rotational motion of the engine is converted into linear motion through the transmission, which then propels the car forward. Similarly, in a blender, the rotational motion of the blades is converted into linear motion to mix and blend ingredients.
